This paper is concerned with the quaternary nonlinear hyperbolic boundary value problem (QNLHBVP) studding constraints optimal classical continuous control vector (CQOCCCV), cost function (CF), and equality inequality state (EIQSCCV). The existence of a CQOCCCV dominating by QNLHBVP stated demonstrated using Aubin compactness theorem (ACTH) under appropriate hypotheses (HYPs). Furthermore, math...

In this work, we investigated the landscape response to recent activity of faults affecting Catanzaro Trough, a seismically active structural basin that developed transversally Calabrian Arc (Southern Italy) during Neogene–Quaternary. We carried out geomorphological and morphometric study drainage networks basins intercepted by Quaternary were previously mapped through remote field analyses. Th...

results of total 60 s. aureus isolates, 51 (85%) were mrsa, and of 60 cons, 7 (11.66%) were mrcons. the results showed that the mic of chlorhexidine for all 120 isolates was 1-16 μg/ml. 15 (12.5%) isolates carried qaca/b gene, 26 (21.7%) carried qacc gene, and 38 (31.7%) carried smr gene. conclusions maintenance of mrsa isolates in the attendance of low amounts of antiseptics could result in th...

Derivatization of peptides as quaternary ammonium salts (QAS) is a promising method for sensitive detection by electrospray ionization tandem mass spectrometry (Cydzik et al. J. Pept. Sci. 2011, 17, 445-453). The peptides derivatized by QAS at their N-termini undergo fragmentation according to the two competing mechanisms - charge remote (ChR) and charge directed (ChD). The absence of mobile pr...

In this paper, we propose multicode multiple-input multiple-output (MIMO) systems with quaternary low correlation zone (LCZ) and zero correlation zone (ZCZ) sequences as spreading codes. Quaternary LCZ and ZCZ sequences have very low correlation values when the time shifts of correlation function are within the predetermined correlation zone and thus the multiuser or multipath interference can ...

Eight quaternary ammonium compounds were tested for their ability to induce contact dermatitis in guinea pigs by using a modified Freund's complete adjuvant test together with the guinea pig maximization test. Only two quaternary ammonium salts of the eight tested could be designated as strong allergens. These two active substances were shown to be capable of stable association with membrane li...
